C and AWK questions

[chris at umcp-cs.UUCP]

The 4.2BSD malloc has (if what I've been told is correct) a range
checking option that will cause ``free'' and ``realloc'' to abort
if the area allocated has been overflowed.  I've never seen a
version of malloc & friends that allows one to insert calls to
malloc-checking routine as desired, although it shouldn't be too
hard to write.

If anyone is interested, I have a modified version of the CalTech
power-of-two malloc (the same one as used in 4.2BSD) with range
checking which works properly even on Pyramids, which I could
probably post.
